Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and principle of work, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, Fig. 2, the utility model are that a kind of blast furnace gas diffuses facility, comprise blast furnace gas pipeline 11, gas bleeding valve 12, diffuse tower 10.
In order to solve the problem that exists at the described present known technology of this specification sheets background technology part and to overcome its defective, realization can be cut off coal gas to the passage that diffuses tower when coal gas need not diffuse, stop gas leak; Automatically diffuse simultaneously the goal of the invention of pressure release when gas pressure moment superelevation, the technical scheme that the utility model is taked is:
As Fig. 1 with to shown in Figure 2, this blast furnace gas provided by the utility model diffuses facility, at described gas bleeding valve 12 and diffuse on the pipeline between the tower 10 anti-leak water seal 1 is set.
Adopt technique scheme, diffusing valve 12 backs at emission coal gas increases by a device, i.e. anti-leak water seal 1, and this device can cut off gas bleeding valve 12 to the passage that diffuses tower 10 when coal gas need not diffuse, stop gas leak; While releasing pressure automatically when gas pressure moment superelevation; Simultaneously, this device lifetime is long, and is durable in use.
Under the nervous situation of blast furnace gas, close this and put gas bleeding valve 12, water is filled in anti-leak water seal 1, guarantee that blast furnace gas does not have leakage.Blast furnace gas enters coal gas diffusion tower 10 by DN900, DN400 and gas bleeding valve 12 through coal gas anti-leak water seal 1 and diffuses from blast furnace gas pipeline 11.Close DN900 under the normal circumstances, DN400 diffuses valve, closes anti-leak water seal 1 and leads to the communicating valve that diffuses tower 10, cuts off gas flue.
During pipe network gas pressure superelevation, the gas bleeding valve 12 on electric opening DN900, the DN400, anti-leak water seal 1 is breakdown, and gas flue is opened, and diffuses automatically.
When anti-leak water seal 1 need reseal coal gas, open the bottom connection and diffuse tower 10 valves, diffuse tower 10 water and enter into water seal, close this valve, carry out make up water by condensate make-up piping when anti-leak water seal 1 water level is not enough.
Water in the anti-leak water seal 1 enters by water seal gas exit pipeline 7 and diffuses tower bottom.
In use, pour water a large amount of coal gas of leaking in the process of anti-leak water seal 1 are caused make up water to be brought into to diffuse in the tower 10, moisturizing difficulty, result of use are subjected to certain influence.
In order to solve the problem of above existence, diffusing tower 10 to increasing DN150 connection gate valve---water seal communicating valve 9 between the anti-leak water seal 1 one, when anti-leak water seal 1 is not advanced in the make up water filling, with this valve open, with bring into the water that diffuses in the tower 10 through this valve return in anti-leak water seal 1, assurance anti-leak water seal 1 can be accomplished timely moisturizing, has reached the sealing coal gas purpose of expection.Reduced entering the waste water that diffuses tower 10 in a large number and efflux simultaneously, this water reusable edible has reduced the waste water water displacement, plays the environmental protection effect.
In the prior art, the pipeline behind the gas bleeding valve 12 directly links to each other with coal gas diffusion tower 10; The pipeline that the utility model will directly link to each other cuts off, and increases coal gas anti-leak water seal 1.In addition, in order to utilize the water in the water seal, reduce waste water and efflux, diffusing increase by one unicom pipeline between tower 10 and the anti-leak water seal 1, this coupling cock is closed when filling water cut-out coal gas in anti-leak water seal 1; When the water seal pressure release, big water gaging enters into and diffuses tower 10, when anti-leak water seal 1 need pour water again cut off coal gas before, open this coupling cock, make and diffuse in the tower 10 water and get back in the anti-leak water seal 1.
When in this anti-leak water seal 1 when anhydrous, coal gas enters into from outlet conduit through cylindrical shell by inlet pipeline and diffuses tower 10.
This passage is cut off when filling water in the anti-leak water seal 1, and coal gas is shut leaks nothing.
Said structure plays the effect of sealing.
Establish wash water valve 5 in the bottom of water-sealed cylinder 3 described in the utility model.After producing for some time, the bottom of water-sealed cylinder 3 can deposit a lot of dirts, at this moment, opens wash water valve 5, discharges dirt.
Establish filling pipe 6 on the top of water-sealed cylinder 3 described in the utility model.
If it is not enough to add in the anti-leak water seal 1 water yield,, make the water level in the anti-leak water seal 1 reach virtual height with opening filling pipe 6 make up water that connect people's anti-leak water seal 1 from the outside.
Establish the water level gauge 4 of clear tubular in the outside of water-sealed cylinder 3 described in the utility model, the two ends up and down of described water level gauge 4 are communicated with the top and the bottom of described water-sealed cylinder 3 by pipeline respectively.In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
